Channel 4 news reporter Michael Crick used the opportunity of a one-on-one interview to question the prime minister about what she had done to oppose racial segregation in South Africa, which was only ended in the country in the early 90s.

During the two-minute grilling, May was repeatedly interrupted and refused to give a straight answer to the journalist’s line of questioning, although she admitted that she had not personally taken part in protests against South Africa’s white-only regime.

“Mrs Thatcher believed that Nelson Mandela was a terrorist…Did you think the same thing?”@Theresa_May is questioned by @MichaelLCrick about her stance on apartheid ahead of her visit to Robben Island, where Mandela was imprisoned.

“You were active in politics in the 70s and 80s, what did you do to help release Nelson Mandela?” Crick asked.

May responded: “I think what is important is what the United Kingdon-”

But Crick interrupted the prime minister, repeating: “No, what did you do? Did you go on protests? Did you get arrested outside the embassy? Did you boycott South African goods? Did you do anything?”

She replied: “I think you know full well, Michael, that I didn’t go on protests. But what is important is the work that –

“Well did you boycott South African goods?” Crick interrupted again. Only for May to continue: “The work that the United Kingdom government did to ensure that it did give support where that support was needed.”

Although not a member of parliament until 1997, Theresa May was an active Conservative politician and party member during the 1980s and served as a councillor for London Borough of Merton from 1986 to 1994.

Margaret Thatcher attracted criticism during her premiership of the country in the 80s for dismissing the then incarcerated Nelson Mandela as “a terrorist”. Following the end of his 18-year imprisonment, Mandela would go on to become President of South Africa from 1994 to 1999.

Turning to the record of the Tory government at the time, Crick asked: “Hang on a minute at that stage Mrs Thatcher believed that Nelson Mandela was a terrorist. Were you a loyal Conservative member, did you think the same thing?”

May responded: “What was important was the support that the government was giving at the time, often support behind the scenes to ensure that we saw the result that we did in relation to the ending of apartheid here in South Africa.”

Theresa May later visited the deceased former South African president’s cell on Robben Island. Upon leaving the island, she wrote in the visitor book: “It has been a privilege to visit in this year – the 100th anniversary of the birth of Nelson Mandela.

“His legacy lives on in the hopes and dreams of young people here in South Africa and around the world.”
